Try some javascript debugging. Put in a javascript sentence in the
javascript method ev_command_enter:
alert("wrong number of ajax results");
This will confirm that at least javascript is seeing the event.
There might be hints in the jijx window.
Using submit() in the handler is probably wrong. Follow the pattern
from other JHS pages that work.
